A City Sleeps is a musical 'bullet hell' shooter from Harmonix

PAX Prime hasn't started yet, but that hasn't stopped Harmonix from revealing their latest game. The creators of Rock Band and Dance Central have unveiled a new twin-stick shooter called A City Sleeps, adding bullet hell shooting to their musical resume.

A City Sleeps centers around a girl named Poe, who enters people's dreams to remove the demons that dwell within them with the air of her Koto-sword called "Heartstrings." The anime-style action game promises hardcore twin-stick shooting with tactical choices. And as has become the hallmark of Harmonix, much of the action, including enemy spawning and movement patterns, will be driven by the game's soundtrack.
